Is it possible to display the strings that match a regular expression?
Example:
Take the expression /^AD\d{3}/
and display AD999
What I'm doing is validating a string that is pretty simple either containing all numbers, a few characters maybe, and maybe a '-'. I am validating a postal code on form submit against a database of all countries that use a postal code.
I could perform it in Javascript or PHP, if that makes any difference.

Regex examples. A simple example for a regular expression is a (literal) string. For example, the Hello World regex matches the "Hello World" string. . (dot) is another example for a regular expression.
A regular expression followed by an asterisk ( * ) matches zero or more occurrences of the regular expression. If there is any choice, the first matching string in a line is used.
Example : ^\d{3} will match with patterns like "901" in "901-333-". It tells the computer that the match must occur at the end of the string or before \n at the end of the line or string. Example : -\d{3}$ will match with patterns like "-333" in "-901-333". A character class matches any one of a set of characters.
No. That sort of feature is not available.
You can try to implement it yourself, but I don't think that's the solution for you. Simply write the messages normally. Not everything must always be dynamic.
I like your way of thinking though.
